A standard gasoline-powered car with a 122L capacity at 30mpg would be capable of traveling 960 miles.
What kind of "standard gasoline-powered car" that runs at 30mpg (forget about the odd units) has a 122L gas tank!?
My car only has 42L... I know larger cars would have bigger tanks, but likely don't get 30mpg.
So if we compare more realistic sizes with their weird mix of L and miles... A 42L tank might get 330 miles... Maybe better to compare with that. But then that wouldn't be highway driving... which I know I can do better then 30mpg.
